the real world study of neoadjuvant immunotherapy in early stage nsclc in china

Conditions: Immunotherapy; Lung Cancer

Summary: several published clinical trials have shown the superiority of immunotherapy in neoadjuvant setting. here we conducted this real world study to see whether neoadjuvant immunotherapy would bring mpr and survival benefits in nsclc, for example, single agent immunotherapy or immunotherapy combination with chemotherapy. furthermore biomarker analysis would be also performed to achieve personalized neoadjuvant immunotherapy.
